Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a portable integrated thoracentesis device. Background Technology

[0002] Thoracentesis is a medical procedure used to diagnose or treat conditions such as pleural effusion and pneumothorax. Before the procedure, the physician assesses the patient, uses ultrasound to locate the puncture site, and the patient faces a chair back with their forearm resting on the back and forehead reclining. The skin is disinfected with iodine solution centered on the puncture site, a sterile drape is applied, and local anesthesia is administered. After ultrasound-guided insertion into the pleural cavity, a soft guidewire is advanced through the needle core. The guidewire is secured, and the needle is withdrawn. A drainage tube is then inserted along the guidewire to an appropriate depth, after which the guidewire is removed, leaving the drainage tube in the pleural cavity and securely fixed. The end of the drainage tube is connected to a sterile water-seal bottle for collecting gas or a drainage bag for collecting effusion, which is then collected and sent for testing. Therefore, currently, completing a single thoracentesis procedure in clinical practice requires multiple steps and various instruments. This method is time-consuming, labor-intensive, and inefficient. Furthermore, it may delay treatment in emergencies. When a patient experiences an emergency (such as tension pneumothorax) requiring thoracentesis, rapid completion of the procedure is crucial.

[0003] Therefore, the present invention provides a portable integrated thoracentesis device to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a portable integrated thoracentesis device. By setting up an auxiliary puncture unit, medical staff can quickly insert the puncture needle and drainage tube into the patient's chest cavity at the same time, saving time and effort and effectively improving the work efficiency of medical staff. The above settings can solve the problem that medical staff need multiple steps and multiple instruments to complete the puncture work during thoracentesis.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A portable thoracentesis device includes a housing, characterized in that it further includes an auxiliary puncture unit installed inside the housing. A base is slidably connected to the bottom of the housing, a scale is provided on the base, a first limiting block is fixedly connected to the base, and a third limiting block and a fifth limiting block are fixedly connected to the inner side of the housing. The first limiting block is used to limit the auxiliary puncture unit. The auxiliary puncture unit is used to insert a drainage tube and a puncture needle into the patient's body, with the drainage tube sleeved over the puncture needle.

[0007] Optionally, the auxiliary puncture unit includes a catapult frame slidably connected within the housing. The catapult frame includes a top horizontal plate slidably connected within the housing. A fixing groove is fixedly connected to the top of the top horizontal plate. A first limiting groove is formed on the top horizontal plate. The fixing groove and the first limiting groove protrude outside the housing. A catapult vertical plate is fixedly connected to the bottom of the top horizontal plate. A catapult horizontal rod is fixedly connected to the top of the catapult vertical plate. A limiting protrusion is fixedly connected to the end of the catapult horizontal rod away from the catapult vertical plate. A bottom horizontal plate is fixedly connected to the bottom of the catapult vertical plate. A second spring is sleeved on the catapult horizontal rod. The catapult vertical plate and the fifth limiting block are provided at both ends of the second spring. The catapult horizontal rod is inserted into the second limiting block. A third spring is fixedly connected to the top of the second limiting block. The end of the third spring away from the second limiting block is fixedly connected to the inner wall of the housing.

[0008] Optionally, a limiting buckle is fixedly connected to the top of the first limiting groove.

[0009] Optionally, the outer casing is provided with a third limiting block, a reset crossbar is inserted into the third limiting block, a first spring is sleeved on the reset crossbar, a reset seat is fixedly connected to one end of the reset crossbar, and the two ends of the first spring are fixedly connected to the reset seat and the third limiting block.

[0010] Optionally, a buffer pad is inserted at the end of the reset crossbar away from the reset seat.

[0011] Optionally, a fourth limiting block is fixedly connected to the outer shell, a cover plate is installed inside the fourth limiting block, and a support frame and a skin-breaking seat are rotatably connected to the end of the cover plate away from the fourth limiting block.

[0012] Optionally, a piercing needle is inserted into the piercing seat.

[0013] Optionally, a pusher is fixedly connected to the piercing needle.

[0014] Optionally, a second limiting groove is provided on the outer casing.

[0015] Optionally, a connecting tube is sleeved on the drainage tube.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up an auxiliary puncture unit, medical staff press the second limiting block upwards, causing the cavity on the second limiting block to move upwards. At this time, the second limiting block no longer limits the limiting protrusion. As a result, the second spring, which is under compression, rebounds due to its elasticity, causing the ejector frame to move rapidly towards the puncture needle, thereby driving the puncture needle and drainage tube to be quickly inserted into the patient's chest cavity. In this way, the auxiliary puncture unit can quickly insert the puncture needle and drainage tube into the patient's chest cavity at the same time, saving time and effort, effectively improving the work efficiency of medical staff, and can be quickly completed when the patient has an emergency requiring thoracentesis.

[0018] By setting up a skin-piercing seat, a skin-piercing needle, and a pusher, the support frame is first placed on both sides of the patient's puncture point to position the entire device and prevent displacement during puncture, which would affect the puncture effect. The skin-piercing seat is then rotated to a horizontal position, and the medical staff pushes the pusher to pierce the patient's surface skin. Then, the pusher is pulled back and the skin-piercing seat is rotated to a vertical position to prepare for the subsequent insertion of the puncture needle and drainage tube into the patient's body. This method eliminates the need for multiple instruments to assist in the puncture, saving time and effort.

[0019] By setting a fixed groove, a first limiting groove, a second limiting groove, and a cover plate, the trajectory of the puncture needle and drainage tube can be fixed during the puncture process, ensuring stable insertion into the puncture point.

[0020] By incorporating a reset crossbar, a first spring, a reset seat, a third limiting block, and a buffer pad, after medical personnel complete the puncture procedure, they press the second limiting block with their left hand and the reset seat with their right hand, causing the reset crossbar and buffer pad to move. The buffer pad then moves the ejector frame, which in turn causes the limiting protrusion and ejector crossbar to pass through the cavity of the second limiting block. Releasing the pressure on the second limiting block causes the third spring to regain its elasticity, causing the second limiting block to move downwards, thus fixing the limiting protrusion for subsequent use. This device has a simple structure, is easy to operate, and effectively improves the work efficiency of medical personnel. Attached Figure Description

[0036] like Figures 1 to 6 As shown, an embodiment of the present invention provides a portable thoracentesis device, including a shell 1 and an auxiliary puncture unit. A base 2 is slidably connected to the bottom of the shell 1. A scale 3 is provided on the base 2. A first limiting block 14 is fixedly connected to the base 2. A third limiting block 26 and a fifth limiting block 30 are fixedly connected to the inner side of the shell 1. The fifth limiting block 30 and the third limiting block 26 are respectively located on both sides of the first limiting block 14.

[0037] The auxiliary puncture unit is used to insert the drainage tube 11 and the puncture needle 32 into the patient's body. The drainage tube 11 is sleeved outside the puncture needle 32. The auxiliary puncture unit is connected to the outer shell 1. The drainage tube 11 is sleeved and connected to the connecting tube 12. Before thoracentesis, medical staff confirm the puncture point and puncture depth through medical imaging. By setting the first limiting block 14 and the scale 3 on the base 2, the forward ejection distance of the auxiliary puncture unit can be limited. In this way, the puncture needle 32 and the drainage tube 11 can be accurately inserted into the patient's required position. Then, the portable thoracentesis device is removed, the puncture needle 32 is pulled out, and the drainage tube 11 is left in the patient's body and fixed. Then, the connection tube 12 is used to connect to a sterile water-seal bottle for collecting gas or a drainage bag for collecting effusion for collection and testing.

[0038] like Figures 3 to 5 As shown, the auxiliary puncture unit includes a catapult frame 15 slidably connected within the outer casing 1. The catapult frame 15 includes a top horizontal plate 23 slidably connected within the outer casing 1. A fixing groove 24 is fixedly connected to the top of the top horizontal plate 23 for placing the handle of the puncture needle 32. A first limiting groove 25 is provided on the top horizontal plate 23. A catapult vertical plate 20 is fixedly connected to the bottom of the top horizontal plate 23. A catapult horizontal bar 21 is fixedly connected to one side of the catapult vertical plate 20. A limiting protrusion 22 is fixedly connected to the end of the catapult horizontal bar 21 away from the catapult vertical plate 20. A bottom horizontal plate 19 is fixedly connected to the bottom of the catapult vertical plate 20. A second spring 16 is sleeved on the catapult horizontal bar 21. The catapult vertical plate 20 and a fifth limiting block 30 are provided at both ends of the second spring 16. The second spring 16 and the limiting protrusion 22 are on both sides of the fifth limiting block 30. In the initial state, the fifth limiting block 30 abuts against the second spring 16.

[0039] The ejection crossbar 21 is inserted through the second limiting block 17. The limiting protrusion 22 and the fifth limiting block 30 are located on both sides of the second limiting block 17. The top of the second limiting block 17 is fixedly connected to the third spring 18. The end of the third spring 18 away from the second limiting block 17 is fixedly connected to the outer shell 1. The top of the first limiting groove 25 is fixedly connected to the limiting buckle 13. The head of the outer shell 1 is provided with the second limiting groove 31, with the direction of the limiting protrusion 22 as the tail of the outer shell 1.

[0040] The top horizontal plate 23 and the bottom horizontal plate 19 are slidably connected to the grooves opened inside the outer shell 1. The grooves can limit the top horizontal plate 23 and the bottom horizontal plate 19 to slide laterally along the grooves, thereby ensuring that the ejector frame 15 can drive the puncture needle 32 and the drainage tube 11 to be inserted stably and accurately into the patient's body. The bottom of the second limiting block 17 penetrates the bottom of the outer shell 1 and protrudes outside the outer shell 1. A cavity is opened on the second limiting block 17, and the ejector crossbar 21 passes through the cavity. In the normal position, the top wall of the ejector crossbar 21 abuts against the top inner wall of the cavity to limit the limiting protrusion 22.

[0041] Medical staff press the second limiting block 17 upwards, causing the cavity on the second limiting block 17 to move upwards. At this time, the second limiting block 17 no longer limits the limiting protrusion 22. As a result, the second spring 16, which is under pressure, causes the ejector frame 15 to move rapidly towards the piercing needle 7 due to its elastic rebound. The direction of the piercing needle 7 is located in the direction of the head of the outer shell 1. The fifth limiting block 30 limits the ejector frame 15 to move towards the tail direction, and does not limit it in the opposite direction.

[0042] This causes the puncture needle 32 and drainage tube 11 to move rapidly toward the puncture needle 7, thereby assisting the puncture unit in quickly inserting the puncture needle 32 and drainage tube 11 into the patient's chest cavity simultaneously. This portable integrated thoracentesis device has a simple structure and is easy to operate, which can effectively improve the work efficiency of medical staff. It does not require medical staff to complete the procedure with multiple steps and instruments as in traditional thoracentesis. At the same time, when a patient has an emergency and needs thoracentesis, this portable integrated thoracentesis device can complete the procedure quickly.

[0043] like Figure 3 and Figure 4 As shown, the reset structure includes a reset crossbar 27, the third limiting block 26 inserts the reset crossbar 27, the reset crossbar 27 is fitted with a first spring 10, the end of the reset crossbar 27 is fixedly connected to a reset seat 9, the two ends of the first spring 10 are fixedly connected to the reset seat 9 and the third limiting block 26, the end of the reset crossbar 27 away from the reset seat 9 is inserted with a buffer pad 28, the buffer pad 28 is made of soft rubber, when the ejector 15 is ejected at a relatively fast speed and hits the reset crossbar 27, the buffer pad 28 can play a buffering role and reduce equipment damage. The head side wall of the outer shell 1 is provided with a hollow so that the reset seat 9 is exposed outside the outer shell 1.

[0044] When the ejection vertical plate 20 at the end of the ejection frame 15 contacts the buffer pad 28 and the ejection frame 15 is to be limited, the medical staff presses the second limiting block 17 with their left hand and the reset seat 9 with their right hand, which moves the reset crossbar 27 and the buffer pad 28 toward the second limiting block 17. The buffer pad 28 moves the ejection frame 15, which in turn moves the limiting protrusion 22 and the ejection crossbar 21 through the cavity of the second limiting block 17. At this time, the pressure on the second limiting block 17 is released. As the third spring 18 recovers its elasticity, the second limiting block 17 moves down, thus completing the fixation of the limiting protrusion 22.

[0045] like Figures 1 to 3As shown, a fourth limiting block 29 is fixedly connected to the outer shell 1. The fourth limiting block 29 is located at one end of the second limiting groove 31 near the tail of the outer shell 1. A cover plate 4 is installed inside the fourth limiting block 29. After installation, the cover plate 4 is located on the second limiting groove 31. A support frame 5 and a puncture seat 6 are rotatably connected to the end of the cover plate 4 away from the fourth limiting block 29. A puncture needle 7 is inserted into the puncture seat 6. A pusher 8 is fixedly connected to the puncture needle 7. Before puncture, the medical staff inserts the puncture needle 32 into the drainage tube 11, and then inserts the handle of the puncture needle 32 from the handle end, i.e., the tail of the outer shell 1, into the fixing groove 24, and then passes through the first limiting groove 25 and the second limiting groove 31 in sequence. 1 is used to limit the puncture needle 32 and drainage tube 11. Then, the upper limit buckle 13 is engaged, and the cover plate 4 is placed inside the fourth limiting block 29 and fixed to the outer shell 1. This ensures that the puncture needle 32 and drainage tube 11 have a fixed trajectory during puncture and are stably inserted into the puncture point. Before puncture, the medical staff first places the support frame 5 on both sides of the patient's puncture point, which can play a role in positioning the entire device to prevent the device from shifting during puncture and thus affecting the puncture effect. The skin-piercing seat 6 is rotated to a horizontal position. The medical staff pushes the pusher 8 to make the skin-piercing needle 7 pierce the surface skin of the patient's puncture point, and then pulls back the pusher 8 and rotates the skin-piercing seat 6 to a vertical position (e.g., Figure 2 As shown in the figure, this prepares for the subsequent insertion of the puncture needle 32 and drainage tube 11 into the patient's body, so that the puncture can be completed without the assistance of multiple instruments, saving time and effort. The puncture needle 32 has a handle at the tail end, which protrudes from the drainage tube 11.

[0046] The working principle of the technical solution provided by this invention is as follows:

[0047] During use, medical staff assess the patient before the procedure and use ultrasound to locate the puncture point and depth. A first limiting block 14 and a scale 3 on the base 2 limit the forward ejection distance of the auxiliary puncture unit. Sliding the base 2 moves the first limiting block 14 to determine the movement distance of the ejector frame 15, thus accurately inserting the puncture needle 32 and drainage tube 11 into the desired position on the patient. The medical staff presses the second limiting block 17 with their left hand and the reset seat 9 with their right hand, moving the reset crossbar 27 and the buffer pad 28. The buffer pad 28 contacts and moves the ejector frame 15, which in turn moves the limiting protrusion 22 and... The ejector bar 21 passes through the cavity of the second limiting block 17. At this point, the pressure on the second limiting block 17 is released, and the second limiting block 17 moves downwards due to the return of elasticity of the third spring 18, thus fixing the limiting protrusion 22. The puncture needle 32 is inserted into the drainage tube 11. Then, the handle of the puncture needle 32 is placed from the handle end into the fixing groove 24, and then passes through the first limiting groove 25 and the second limiting groove 31 in sequence. The upper limit buckle 13 is then engaged, and the cover plate 4 is placed into the fourth limiting block 29 and fixed to the outer shell 1. This ensures that the puncture needle 32 and the drainage tube 11 maintain a fixed trajectory during puncture, ensuring stable insertion. Before puncture, medical staff place the support frame 5 on both sides of the puncture point to position the entire device and prevent displacement during puncture, which could affect the puncture effect. The skin-piercing seat 6 is rotated to a horizontal position. The medical staff pushes the pusher 8 to allow the skin-piercing needle 7 to puncture the patient's surface skin. Then, the pusher 8 is pulled back, and the skin-piercing seat 6 is rotated to a vertical position to prepare for the subsequent insertion of the puncture needle 32 and drainage tube 11 into the patient's body. During puncture, the medical staff presses upward on the second limiting block 17, causing the cavity on the second limiting block 17 to move upward. At this point, the second limiting block 17 no longer limits the limiting protrusion 22. The second spring 16, under compression, rebounds elastically, causing the ejector frame 15 to move rapidly toward the puncture needle 7, thereby quickly inserting the puncture needle 32 and drainage tube 11 into the patient's chest cavity. This assists the puncture unit in quickly inserting the puncture needle 32 and drainage tube 11 into the patient's chest cavity simultaneously. Then, rotate the support frame 5 to a vertical position and lift it up to remove the cover plate 4. Open the limit buckle 13, remove the entire device, then pull out the puncture needle 32 while leaving the drainage tube 11 in the patient's body and securing it. Then, connect the connecting tube 12 to a sterile water-seal bottle for collecting gas or a drainage bag for collecting effusion for collection and testing.
